Install a processor-heat-sink module

The processor and heat sink are removed together as part of a processor-heat-sink-module (PHM) assembly. PHM installation requires a Torx T30 driver.

If you are installing multiple options relating to the system board, the PHM installation should be performed first.
  • Each processor socket must always contain a cover or a PHM. When removing or installing a PHM, protect empty processor sockets with a cover.

  • Do not touch the processor socket or processor contacts. Processor-socket contacts are very fragile and easily damaged. Contaminants on the processor contacts, such as oil from your skin, can cause connection failures.

  • Remove and install only one PHM at a time. If the system board supports multiple processors, install the PHMs starting with the first processor socket.

  • Do not allow the thermal grease on the processor or heat sink to come in contact with anything. Contact with any surface can compromise the thermal grease, rendering it ineffective. Thermal grease can damage components, such as electrical connectors in the processor socket. Do not remove the grease cover from a heat sink until you are instructed to do so.

  • Thermal grease can stay functional on the heat sink for two years. When installing a new heat sink, make sure to check the manufacturing date to ensure the thermal grease is still functioning. If the date is over two years ago, replace the thermal grease to avoid seating issues.
  • PHMs are keyed for the socket where they can be installed and for their orientation in the socket.

  • See Lenovo ServerProven website for a list of processors supported for your system. All processors on the system board must have the same speed, number of cores, and frequency.

  • Before you install a new PHM or replacement processor, update your system firmware to the latest level. See Update the firmware.

  • Installing an additional PHM can change the memory requirements for your system. See Install a memory module for a list of processor-to-memory relationships.

  • Optional devices available for your system might have specific processor requirements. See the documentation that comes with the optional device for information.

  • The following types of heat sinks are applicable to SD530:

    • Low voltage configuration

      • 108x108x24.5mm heat sink is only applicable to processor socket 1.

      • 85x108x24.5mm heat sink is only applicable to processor socket 2.

    • High voltage configuration

      • T-shaped heat sink is only applicable to processor socket 1.

      • 105x108x24.5mm heat sink is only applicable to processor socket 2.

Before installing a PHM:
The PHM for your system might be different than the PHM shown in the illustrations.
  1. Read the following section(s) to ensure that you work safely.
  2. Turn off the corresponding compute node that you are going to perform the task on.

  3. Remove the compute node (see Remove a compute node from the enclosure).
  4. Remove the compute node cover (see Remove the compute node cover).
  5. Remove the air baffle (see Remove the air baffle).
  1. Remove the processor socket cover, if one is installed on the processor socket, by placing your fingers in the half-circles at each end of the cover and lifting it from the system board.
  2. If the processor comes with a T-shaped hear sink, secure the heat sink with two screws on the sides of the node.

    Use Phillips #1 driver on these two screws.
  3. Install the processor-heat-sink module on the system board.
    Figure 3. Installing a PHM
    PHM installation
    1. Align the triangular marks and guide pins on the processor socket with the PHM; then, insert the PHM into the processor socket.
      To prevent damage to components, make sure that you follow the indicated tightening sequence.
    2. Fully tighten the Torx T30 captive fasteners in the installation sequence shown on the heat-sink label. Tighten the screws until they stop; then, visually inspect to make sure that there is no gap between the screw shoulder beneath the heat sink and the processor socket. (For reference, the torque required for the nuts to fully tighten is 1.4 - 1.6 newton-meters, 12 - 14 inch-pounds).
After installing the PHM option:
  1. If there are memory modules to install, install them. See Install a memory module.

  2. Reinstall the air baffle (see Install the air baffle).

  3. Reinstall the compute node cover (see Install the compute node cover).

  4. Reinstall the compute node (see Install a compute node in the enclosure).

  5. Check the power LED to make sure it transitions between fast blink and slow blink to indicate the node is ready to be powered on.
